Dead Sun - Midnight-Region - Scenery

The region covering half of the tidal-locked planet, that never sees the sunlight. This is the region where humanity been pushed back by the advenas, being forced to live on these inhospitable lands. It is cold and pitch-dark, therefore humanity had to adapt and develop their light-source technology for the cities, roads, and for the military as well. They using motion-sensing light-sources to signal where the roads are to navigate between settlements, that are all surrounded by tall walls, and spotlights to defend against the terrorizing advena forces.
